NEW ORLEANS (AP) A man convicted in the shooting death of retired New Orleans Saints star Will Smith has appealed the conviction and 25-year-sentence arising from a confrontation after a 2016 traffic collision.

Cardell Hayes was convicted of manslaughter in December 2016 in Smith's death and of attempted manslaughter because Smith's wife, Raquel, was shot in both legs during the encounter in April of that year.

But Hayes' attorney Paul Barker wrote in an appeal filed Thursday that the judge who tried Hayes should have granted a new trial because a witness who contacted Barker the day after Hayes' conviction said he had heard two guns at the time of the shooting, buttressing Hayes' claim that he had fired in self-defense.
